STATISTICAL ANALYSIS OF FLOWING ARTESIAN WELLS DURING WINTER AND SUMMER SEASON

Abstract

The study was conducted with the aim to analyse the co-relation and multiple linear regression analysis of water quality of flowing artesian wells located in the vicinity of Pantnagar University campus in winter season and summer season. These samples were analysed for various parameters such as pH, electric conductivity (EC), total dissolved solid(TDS), total hardness (TH), calcium hardness (Ca2+), magnesium hardness (Mg2+), sodium (Na+), potassium (K+), bi-carbonate (HCO3-), acidity, alkalinity, chloride, fluoride, nitrate, carbon di-oxide (CO2) and sulphate (SO4). In Statistical data analysis the r value between is EC-TDS, EC-Acidity, TH-Ca, TH-Mg and Alkalinity- HCO3, shows the significantly strong positive relationship at 0.01 level in during winter season and summer season the correlation analysis between EC- TDS, TH-Ca, TH- Mg, EC-alkalinity, TDS- alkalinity, EC-HCO3, TDS- HCO3, alkalinity-HCO3, EC- Cl, TDS-Cl, alkalinity-Cl-, HCO3--Cl-, acidity-fluoride and acidity-CO2 shows the significantly strong positive relationship at 0.01 level. The relationship developed between TDS and different values of pH, EC, Ca++, K+, acidity, chloride and sulphate which can be used to evaluate the ground water quality.
